Application led January 14, 1916. Serial No. 72,073.

To all whom it may concern.' f

Be it known that I, JOHN A. Brooms, a citizen of the United States, anda resident of Toledo in the county of Lucas and State of Ohio, haveinvented a certain new and useful Lawn-sprinkling Means; and I do herebydeclare the following to be a full,

`clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains toAmake and use the same, reference being had to the accompanying drawings,and to the characters of reference marked thereon, which form a part ofthis specication.

This invention relates to plumbing devices and particularly to lawnsprinkling means.-

The object of my invention is the provision of an improved lawnsprinkling means having `a fountain or spray head which isnormallydisposed in inoperative position vand is automatically movable toioperative position by the outward pressure atV the Water when turnedon.

A further lobject of my invention is theV provision, in a means of theclass described, of a cap or closure member which is carried by the'fountain or spray head for movements therewith, and is automaticallyoperable to move into and out of casing closing position with respect tothe fountain head when lowered and raised, respectively, whereby toenhance the practicability and commercial value of devices of the classdescribed.l

prisng a plurality of rinkling units having a common source o watersupply.- Fig.

2 is an enlar ed central verticalsection of the upper en of one of theunits embodymg my invention with the movable spray head parts-in loweredposition. Fi 3 is a similar view thereof, with the movab e spray :headparts in full and'raised to operative position respect to the casingmember,

my invention `and -com- Fig. 4 is an enlarged vertical central sectionof the drainage unit of the set with portions broken awa and with themovable spray head arts in lowered inoperative position, and Fig. 5 is aperspective View of the water 'whirling core-piece of the spray headnozzle.

Referring to the drawings, 1 designates a water supply pipe, which isdisposed in the ground preferably below the frost line and 'has a valve2, which is controlled from above the ground by a key4 3 and is operableto close communication between ya portion of the pipe line and thesource of sup ly.

The portion of the pipe line l, the dow of water to which is controlledby the valve 2, has one or more stand-pipes 4: rising therefrom andlocated to snit the desired distribution of water` therefrom. Eachstandpipe 4 is provided at its upper end with a casing head 5, which isprovided at its upper end with an enlarged nozzle-receiving chamber 6,the upper end of which is disposed substantially at the ground level, asshown in Fig. 2. The lower end of the casing head 5 hasits passageseparated from the chamber 6 by a diaphragm or partition 7 havingacentral opening 8 therethrough. The lower end of the casing head 5 isconnected, in.

thevpresent instance, to the upper end of the stand-pipe 4 by a couplingmember 9.

Located within the chamber 6 of the casing head 5 is a nozzle or sprayhead 10 having an vinterior chamber 1l, which is provided at its outerend with a water discharge orice 12 of restricted outwardly flaringform. A core-piece 13 is mounted within the nozzle chamber 11, in thepresent instance having a friction tight fit therein, and is provided,in the present instance, at each end with a conical projection 14, theupper or outer one of which enters the dis- Vcharas orifice 12 and isintended to regulate the charge of water therethrough. It is apparentthat the sizeof the discharge oriinent of the outerend or cap portion ofthe nozzle and the core-piece 13, and such adjustment may. be effectedeither by a A.movement of the core-piece in one direction orl the otherwithin the nozzle, or b an adjustment of the cap member 15 of t `enozzle with respect to its body portion, one being threaded tothe other.The central portion of the core Vpiece 13, which fits the nozzleAchamber 11, closes the passage through said". chamber except for theprovision ofone or ffice 12 may be varied by a relative adjustmore .(twoin the present instance) spiral peripheral grooves 16 in said,core-piece. These grooves extend from one end to the other ofthe bodyportion of the core-piece and cause the water, in its passagetherethrough, to have a whirling action. The rapid whirling of the waterwithin the nozzle coperates with the restricted discharge passage 12 todischarge the water in nely `broken-up spray form. The dischargin of thewater in this finely broken-up orm causes a greater amount of oxygen to-be lcarried therewith into the ground on which the spray falls and istherefore of greater benet to grass or other growing matter.

The nozzle or spray head l0 has a hollow stemy 16' projecting downwardfrom its lower end through the partition opening 8 and with itspassagein communication with the nozzle chamber 11 below the corepiece13. The stem16 is intended to have reciprocatory movements through theopening 8to permit a raising and lowering of the nozzle 10 with respectto the casing 5, and is provided a redetermined distance below thepartition when the nozzle is in its normal lowered position, with anenlargement 17 having ka gasket-faced shoulder 18,'at its upper, end.`Theshoulder 18 is intended to coact with the' partition 7 vwhen thenozzle and stem are raised and to both ylimit the upward movement of thenozzle and lstem andto close communication between the upper and lowerend'portions of the casing passage around'the stem 16. 7 It isfapparentthat when water under pressure is turned into the pipe 1, it will ,p

1 enter theA standards 4 connectedthereto, and

being su its outward passage through the casing 5, nozzle 10 and stem 16will act against the enlarged lower` end 17 ofthe stem and also againstthe core-piece 13 to effect a raising of the nozzle and stem tooperative position, the ermissible out stroke o f the nozzle cient toplace it above the outer end of the casing, as shown 'in Fig. 3.

The passage of the vwater throu 'h the viral grooves 16 of thecore-piece o ten Ito raise and hold tion when in The upper open end ofthe'eiusing'chamv l ber 6 is normally closed by a cap or closure member1 9, which seats at -its edge' within the open end of the casing andispiv'otally carried by the nozzle 10 for swingmg movements in avertical plane with r t thereto.` The closure member 19,.'in epresentinstance, has a pair of spaced jecting down y:from l the een portionthereof, and' pivoted to the nozzle, as at 21,

in straddling relation thereto, thus permittingzthe closure member toswing ward ateither side of the nozzlefwhen the nozzle vis raised toexposed-or operative p f sition above the casing 5.V ,When then e thenozzle in elevated posi-* -or to the number andarrangem 41n 20provinaefnle` again lowers into inoperative position witbin thecasing 5the closure member 19 is drawn thereby intolosing relation to the upperend of the casing, as isl evident. from the drawings. When the nozzle isin raised or operative position `the closure member 19 is disposed atone side thereof and out 'of obstructing relation to the spray that isdischarged from the nozzle. The seatingof the closure member 19 in theupper end portion of the casing 5 limits the lowering movement of thenozzle and'its stem within the casing. l

It is preferable, where a plurality of fountain umts or spray heads areconnected to a.

common supply pipe 1, to adapt one of the uprights of a set to serve asa drainage means for the entire system or set of fountains. For thispurpose the nozzle-receiving chamber of one of the casings 5 is made ofgreater depth than the others, and provided at its'lower end with one ormore laterally extending drainage assages '22., at a point below thefrost lev Inl the present instance, the drainage casing is designated 5,

and its lengthened nozzle c amber is designated 6a (see Fig. 4). Thenozzle stem is correspondingly 1engthened,as shown at 16",

to adapt it to project through the partition 7**` at'the lower end ofthechamber 6 and a desired distance therbelow. The nozzle stem is providedwit an enlargement 17 having`a gasket-:faced l per end for coacting w ththe under side of the partition 7 to close the passageI there througharound the stein 16* when the. nozzle is raised, lthe same as describedwith respect to the other fountain units of the system.

It is apparent that when the valve2 has been closed, water containedinthe stand-' pipe 4 and casing 5l o f each fountain unit will draindownward therefrom through the pipe 1 and thence upward into thedraining unit through the, artition 7 therein and outward tor the so'through the drain-` 1.
